I just switched from Windows to OpenSUSE, and my problem is the following:
Copying is very cpu intensive, the kworker processes starts to use the whole cpu capacity and my system become unresponsive. If I copy with mc, it uses too a lot of cpu with the kworkers, but if I copy with Krusader, Krusader's cpu usage is ok (but not the kworkers!).
When I copy (from one dir to another in the same drive) with Krusader I can see that the transfer rates sometimes goes up in my system irrealy high 60-70MB/s, and sometimes go down to real 20-30MB/sec, and to stalling(!?).

(running badblocks is not cpu intensive, it uses 8% and the kworkers are 0-1%).

I'm using OpenSUSE 12.1, kernel 3.1.9-1.4-desktop x86_64, KDE 4.7.2.
I'm using lvm encrypted volumes.

I tried the kernel-desktop-3.1.10~jng3-3.x86_64 without any luck.

I have a HP 8510p notebook, with Intel(R) Core(TM)2 Duo T9300 @ 2.50GHz, and 8GB RAM.

What can I do, what can be wrong, and how can I fix it?
If you can, please help.

Thank you forward,


(sorry for my poor English)
